TO ALL WHOM IT MAY CONCERN:

Be it known that I, ISAAC DAN, ofA Deposit, in the county of Broome, and in the State of New York, have invented certain newlend useful improvements in'SleighKnees; and do hereby declare that thefollowing is a full, clear, and exact'description thereof, reference being had to the accompanying drawings, and to the'letters of reference marked thereon. p

In the annexed drawings, making part et this specification, A represents the sleigh-runner, andB and C the knee. The knee is composed partly of wood and partly of meta-k B represents the' metal portion, which consists of a T-shaped block, which is secured to the runner, and which is provided with a vertical dove-tailed groove from top to bottom, as seen. The wood portion of the knee isprovided with a square tenon upon its upper end, and with a dove-tailed tenon ou'its lower end, which is made tot snugly in the groove ofthe block B. The blocks B may be cast and secured to the runner by means of-screws or/small bolts.

By this arrangement the runner is mede stronger than if mortised for a tenon on -the knee, and the knees may be more easily and quickly secured to the runner than by the old plan, while at the same time they are as strong and durable. A v

Having thus fully described my invention, what I claim as new, and desire to secure. by Letters Patent, is-

The knee` constructed of wood'and metal in the manner herein set forth, and used with the runner fox-the purpose specied. l

In testimony that I claim the foregoing I lm've hereuntoset my hand and seal this 24th day of April, 1867.l
